Frequently Asked Questions
1-What is uPVC or PVC-U?
UN-Plasticized Poly Vinyl Chloride is obtained from polymerization process of Vinyl Chloride – which is in turn obtained from mixing Ethylene with Sodium Chloride (57%- Common Salt).
2-FIs uPVC suitable for Pakistan?
YES! uPVC is ideal for Pakistan climate which is near tropic and has a high demand for energy conservation. uPVC windows help in controlling the heat coming into the building / home by acting as an insulator. uPVC windows are ideal choice as they can offer U value as low as 0.6 W/m2K for high performance casement windows and 2.4 W/m2K for normal Sliding Windows which is much lower than other type of windows (wood, aluminum, steel, etc.).
3-Doesn’t uPVC become brittle or yellowish after some time?
No!! The Good Quality uPVC profiles are produced from Tropical Blends which have adequate percentage of TiO2 - Titanium Di-Oxide which imparts white color to the profile along with UV / Heat stabilizers which protects the profile from harmful UV Radiations.
4-How exactly does energy saving happen in a window?
The frame and sash material is uPVC which is a non-conductor. It cuts the heat. Frame and sash is multi chambered. It cuts further heat. Tight gasket sealing helps in preventing leakage through the gap between frame and shutter. Multi-point locking system ensures that the shutter and frame are locked and sealed properly.
5-Why do we need steel reinforcements?
Steel provides the necessary tensile strength to uPVC profile to prevent deflection/ deformation against external forces.
6-Is uPVC recyclable?
Yes! uPVC is recyclable. However scrap is not used in profile extrusion to avoid impurities in the main pro-files. Recycled PVC profiles are used in auxiliary profiles which are not exposed or add strength to a win-dow. Some of it is used for producing accessories.
7-Is uPVC Window Fire Resistant?
Oxygen Index of uPVC is 45 – 49; it means it needs nearly 50% oxygen to continuously burn. Atmosphere contains only around 21% Oxygen. Calcium Carbonate and Chlorine in uPVC prevent it from burning and make it self-extinguishing.
8-Are all plastics equal?
No. The great advantage offered by plastics is that they can be custom-engineered for a particular applica-tion. A slight change in a plastic’s molecular structure can result in substantial changes of its properties. That’s why all plastics are not the same, especially when it comes to window profiles.
9-Aren’t uPVC windows all the same?
No. Even outwardly different windows can be completely different on the inside. The quality of the materi-al, stability and durability, design and processing quality are different as are profile design, sealing, and system variety. Expert installation and integration are of paramount importance as well.
10-How can I tell good quality uPVC?
One way to assess the effectiveness of a frame is to examine the thickness (depth from inside to out). Ideal-ly choose 60 mm thickness and ask about the thickness of the uPVC in the frame - a multi-walled (not solid) section should be 1.8 - 2.0 mm.
11-How strong are uPVC Doors & Windows?
They are strong as the formulation & the design of the profile ensure that the profile does not break. Sec-ondly all the uPVC Doors & Windows are reinforced using steel.
12-Will the uPVC Doors & Windows change color?
No. the formulation done in our product is done to ensure that the UV rays of sun do no alter the composi-tion of the profile thus ensuring that the color does not change.
13-How does uPVC Doors & Windows react in fire?
Our uPVC Doors & Windows burns when subjected to flame, but does not burn by itself: The product extin-guishes immediately when the external flame source is removed.
14-Where is uPVC used in construction?
uPVC is as common in pipes, roof gutters, facade cladding, roofing, light-diffusing walls, interior fixtures, cable ducting, and signs as it is in windows and rolling/folding shutters. Its long service life makes it both an economical as well as environmentally safe solution.
15-What types of windows are available?
There´s the traditional casement window - side or top opening (sometimes known as an awning) and these can sit alongside fixed (non-opening) windows. There are also Vertical Sliders; there´s an array of tilt and turn options where windows tilt back for ventilation and then turn to open and most popular sliding win-dows.
16-How about the thermal insulation properties of various window materials?
uPVC and wood provide marked thermal insulation, meaning their thermal conductivity is extremely low. By contrast, the thermal conductivity of aluminum is 1,000 times greater. Cold bridges are generally inter-rupted by using uPVC bars. Apart from the profile design, the type of glazing used is also of paramount im-portance.
17-How much is the per square foot cost of upvc windows and doors? Is uPVC Doors & Windows costlier than other available alternatives?
At Rkitect, you are in the driving seat to customize your windows and doors to best fit your requirements in terms of design, option of glass, glazing, selection of hardware, net provision, decorative bars and eventual-ly your budget etc. Likewise in other products, per square foot rate of upvc products is a function of your specific require-ments. General phenomenon is that larger the size of the window lower will be per square foot rate and vice versa. uPVC Doors & Windows works out cheaper in the long run. Our windows are energy saving windows & can save up to 30 - 35 % electricity. Therefore making the cost of the window free of cost during its lifetime apart from the above these windows do are maintenance free & do not need painting & polishing there-fore reducing the cost one has to incur over a period of time. Our windows do not need any maintenance as they do not warp unlike wooden windows which expand & contract in rainy seasons need regular repair & maintenance. In long term our uPVC Doors & Windows almost return back the initial investment made on them & hence making it free of cost during its lifetime.
